PCF85176

The PCF85176 is designed as one kind of universal LCD drive PCF85176 that generates the drive signals for any static or multiplexed LCD containing up to four backplanes and up to 160 segments. And PCF85176 is compatible with most microprocessors or microcontrollers and communicates via a two-line bidirectional I2C-bus. Communication overheads are minimized by a display RAM with auto-incremental addressing, by hardware subaddressing and by display memory switching (static and duplex drive modes).

Features of the PCF85176 are:(1)Selectable backplane drive configuration: static, 2, 3, or 4 backplane multiplexing;(2)Silicon gate CMOS process;(3)Auto-incremented display data loading across device subaddress boundaries;(4)Display memory bank switching in static and duplex drive modes;(5)Versatile blinking modes;(6)Independent supplies possible for LCD and logic voltages;(7)Wide power supply range: from 1.8 V to 5.5 V;(8)No external components required;(9)Low power consumption;(10)Manufactured in silicon gate CMOS pro.

The absolute maximum ratings of the PCF85176 can be summarized as:(1)supply voltage: -0.5 to +6.5 V;(2)supply current: -50 to +50 mA;(3)LCD supply voltage: -0.5 to +7.5 V;(4)LCD supply current: -50 to +50 mA;(5)input voltage: -0.5 to +6.5 V;(6)input current: -10 to +10 mA;(7)output voltage: -0.5 to +7.5 V;(8)output current: -10 to +10 mA;(9)latch-up current: 200 mA;(10)storage temperature: -65 to +150 °C;(11)operating temperature: -40 to +85 °C.
